After many months of work the 'Lost Sound Search Engine 3' is complete!!! The machine finds faint sounds floating through the air that we can no longer hear. They could be dozens of years old and may have traveled hundreds of miles from their source. Once located, it amplifies these sounds and plays them back for us to hear once again. This weekend you can use the device for yourself in Salina, Kansas during the Smoky Hill River Festival. I hope to travel this piece around a bit so keep an eye out. It may end up in your neck of the woods someday.
